No. 52,106 Claims priority, application Germany Aug. 28, 1959 3 Claims. (Cl. 132-49) The present invention relates to hair nets, and more particularly, the invention is concerned with hair nets made of synthetic threads or fibers by knitting, weaving or other methods known per se.

Conventional hair nets are made of opaque, colored material in a great variety of shades and colors. A very great number of diflerent shades and colors were required since it has always been desirable to produce hair nets the color of which differs as little as possible from the color of the hair of the wearer. In view of the great variety of shades and colors of natural and dyed hair, it was thus necessary to produce or to maintain a stock of hair nets of many different colors and nevertheless, it was not possible to have available hair nets which closely conform to every possible hair color of potential users. Furthermore, even when a reasonably good match between the color of the hair net and the overall color of the hair of the wearer was found, the hair net still would not become substantially invisible when worn, due to the fact that natural hair is not of completely even color and thus certain portions of the hair net might be fully matched while other portions will contrast from the underlying hair and thus become visible. Up to now it was impossible to overcome the above discussed difficulties in matching hair nets to the color of the hair of the potential wearer and as a compromise solution hair nets were produced in about nine colors and it was then attempted to choose in any given case the color which came closest to the respective hair color.

It has also been attempted to produce hair nets of glass clear transparent synthetic threads. It was thought that due to the complete transparency and lack of color of such threads, the hair nets would become invisible and only the underlying hair would be seen. However, it was found that the outline of such colorless hair net threads usually became visible when such hair nets were worn, possibly due to reflection phenomena.

It is therefore an object of the present invention to overcome the above mentioned diificulties encountered in attempts to produce hair nets which when being worn are practically invisible.

It is another object of the present invention to provide a hair net which when worn will be practically invisible within a wide range of hair colors.

Other objects and advantages of the present invention will become apparent from a scription and of the appended claims.

With the above and other objects in view, the present invention mainly contemplates a hair net consisting essentially of threads of tinted, transparent synthetic material.

The single FIGURE is a perspective view of my improved hair net.

According to a preferred embodiment of the present invention, the same comprises as an article of manufacture, a hair net having an edge, and an elongated resilient element being connected along its length to the edge of the hair net, at least the hair net being formed of threads of tinted, transparent, hair color-simulating synthetic polyamide material and the resilient element being of substantially the same color and transparency as the hair net.

Thus, according to the present invention, the hair net which may be a knitted, woven or otheiwise produced hair further reading of the denet, for instance of the type described in my US. Patent No. 2,798,500, is produced of threads of synthetic material, preferably monofilament threads which per se are glass clear and which are coated or tinted with a thin colored layer, preferably of blonde or brown color. The tinting coating is so thin that the major portion of the transparency of the thread is maintained. Preferably, the thus coated thread will absorb between about 5% and 15% of natural day light passing in cross-sectional direction through the same. It is also within the scope of the present invention to produce the tinted, substantially transparent thread by admixing to the synthetic mass from which the thread is to be formed a suitable quantity of yellow or brown coloring material so that the entire mass of the thread-forming material will be tinted instead of applying a tinted coating to the surface of the thread.

Very good results were obtained by producing a hair net according to the present invention in two color shades only, namely blonde-tinted for use with hair of light color, from blonde to light brown, and brown-tinted for use with hair of darker color.

Surprisingly it has been found according to the present invention that the above described hair nets which consist of brownish or yellowish tinted glass clear synthetic threads which retain the major portion of the transparency of uncolored glass clear threads of the same material, will become practically invisible when placed on the hair of a wearer, whereby the brownish tinted hair nets, of course, are used for the darker range of hair colors, while the yellowish or blonde tinted hair nets are used for lighter colored hair. Probably, this is due to the fact that the original hair color which to a considerable extent will be visible through the substantially transparent hair net, will modify the tinting of the threads of the hair net so that as a combined effect the color of the hair net when worn will be only very slightly different from the color of the exposed portions of hair.

Thus it is an advantage of the present invention that notwithstanding the many different shades of hair colors, the hair nets will become substantially invisible and thus that the blonde or brown tinted hair nets, respectively, can be used in combination with a wide range of hair colors. Furthermore, the maintenance of a sufiicient stock of hair nets will be considerably simplified since instead of the conventionally used nine hair nets of different colors, only hair nets tinted in two different shades, namely blonde and brown, will have to be produced and made available for sale. Notwithstanding the fact that it is proposed to make the hair nets according to the present invention available in two colors only, it has been found that an excellent matching and blending of hair nets and hair, so as to make the hair nets practically invisible, is achieved.

The hair nets according to the present invention may be produced with a resilient element along the annular edge of the hair net. One manner in which this can be done is fully described in my Patent No. 2,798,500 (without, however, limiting the present invention to hair nets of the type described in the above-mentioned patent). It is desirable to produce this resilient element of brown or blonde-tinted glass clear resilient threads corresponding to the tinted threads of the hair net.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawing, in which the figure is a schematic illustration of a tinted hair net according to the present invention. As seen in the drawing, the hair net is formed of monofilament glass clear tinted synthetic threads 11. The tinting in accordance with the present invention, may be either in a medium blonde or in medium brown shade and may be applied as a surface coating or by tinting the entire mass from which the threads are formed. Thus, the hair net 10 is formed with the preferably flexible or resilient main hair net portion 11, the edge of which is indicated at 12. An elongated resilient element 13 is connected along its length to the edge 12 in any suitable manner. This elongated element, preferably also consists of tinted transparent synthetic material.

Preferably, the synthetic material of which the threads of the hair net are formed is of the polyamide type, such as monofilament Perlon or nylon threads. Good results were obtained with threads of between 7 and 70 denier, and in very many cases best results were obtained with threads of approximately 11 denier.

.When the tinting is to be produced by a surface coating of the uncolored glass clear transparent thread, such tinting can be produced by dipping the threads into a suitable dye solution or by applying the dye solution y spraying. Very good results were obtained by using solutions of acidic dyes so that during the dyeing process a chemical reaction takes place combining the free sulfonic dye acid with the amino or imino group of the nylon chain molecule. However, other suitable textile dyes may also he used with the notable exception of dye dispersions, particularly pigment dyes, since such dispersed and not dissolved dyes would cause an undesirably great reduction in the transparency of the thus treated threads. Dip dyeing can be carried out in various ways per se known in the art, for instance, the dye solution may be applied under pressure.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of hair nets diifering I from the types described above.

While the invention has been illustrated and described as embodied in a hair net, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, 'the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
